We've got dark stained floorboards in our living room, kind of like a dark oak colour. I'm pretty sure they are just pine floorboards but they are in great nick and look lovely with the dark stain.
I've grown to hate that 80's pale orangey pine look (having had it going on in many houses I've lived in) so it's a really nice change, looks a bit more 'classy' and goes with everything we've had in there so far.
